APPARATUS FOR APPLYING INSECTICIDES OR SIMILAR SUBSTANCES.

SPECIFICATION forming part of Letters Patent No. 514,253, dated February 6, 1894. Application filed April 3, 1893. Serial No. 468,840. (No model.)

. To all whom it may concern,.- ble bulb d, the necks d of which fit tightly Be it known that I, GABRIEL BOAS, of Bosabout the necks of the heads a and b, to ton,county of Suffolk,State of Massachusetts, thereby render the reservoir formed within 55 have invented an Improvement in Apparatus and by the bulb d, air and {luid-tight. The 5 for Applying Insecticides or Similar Subbulb d is provided with an inlet d2 itt'ed with stances, of which the following description, a screw cap d3, through which opening a quanin connection with the accompanying drawtity of insecticide, deodorizing or other subings, is a specitication, like letters on the stance or duid may be placed, the pipe c 6o drawings representing like parts. within said bulb being provided with one or ro This invention relates to apparatus for apmore perforations c through which the conplying insecticide and similar substances to tents of the bulb d may, by the application trees, shrubs, and the like, the principal obof external pressure, be forced into'the conject of the invention being to provide an apducting pipe c. 65 paratus which may be used like an ordinary As herein shown and preferably the head r 5 garden hose and apply'the insecticide or subb is provided with a plug or valve e controlled stance in the form of a spray and yet have by a handle e', by means of whichvthe flow of the apparatus at all times completely under iiuid through the pipe c may be controlled at the control of the operator, whereby the quanwill. 7o tity of the insecticide applied at any time or The operation of my improved apparatus 2o to any particular plant or shrub may be regis as followszF-The insecticide or deodorizing ulated as deemed necessary. or other substance or material which it is de- My'invention consists in an apparatus in sired to apply to the trees or shrubs is placed which an insecticide-containing reservoir is within the bulb d which constitutes the reser`` 75 connected with a iuid conducting pipe, as for Voir, the cap d3 applied to close the entrance 25 instance, an ordinary garden hose, and proopening. The head b is then secured to the viding the apparatus with means for applying nipple on the end of the hose and the water external pressure to the insecticide contained turned on and permitted to flow through in the reservoir, whereby the insecticide northe pipe c and issue at the nozzle, asin the 8o mally retained in the reservoir bythe pressordinary garden hose, the pressure of the 3o ure of the fluid in the conducting pipe may water within said pipe holding back the conbe forced into and mingle with the' fiuid in tents of the bulb and preventing said consaid conducting pipe, as will be more fully tents from mingling with the water passing' hereinafter set forth. through the pipe.v When it is desired .t 8 5 In the drawings, Figure l, represents in apply any of the contents of the bulb to a tre 3 5 longitudinal section one form of apparatus or shrub, the bulb'is compressed by the appli\ embodying this invention; and Fig. 2, a modication of external pressure, which thereby iication to be described. forces more or less of the cont-ents of the bulb I have herein shown and will describe my through the perforations c into the pipe c to 9o invention as constructed to be applied to and mingle with the iluid flowing therethrough 4o used in connection with the usual garden and to be sprayed therewith upon the tree or hose, and referring to the drawings, a andb shrub toward which the nozzle is directed. represent two metallic heads, one of which, as According as the pressure applied to the bulb a, is threaded to receive the usual garden is greater or less so will the quantity of in- 95 spraying nozzle which may be of any desired secticide or deodorizing substance contained 45 shape or construction, while the head b is inwithin the bulb be caused to mingle in greater teriorly threaded at its outer end to receive or less quantities with the water owing the nipple on the end of the garden hose, not through the pipe. shown. These two heads are connected by a In practice, the contents of the bulb or resroo tube c so that a continuous pipe or passage servoir will preferably be colored somewhat 5o leading from the hose to the nozzle is proin order that it may color the spray issuing vided through the heads and the connecting from the nozzle, and thus enable the operator tube. Surrounding the tube c isa compressito determine at all times by the color of the spray, the quantity of insecticide or deodorizing substance which is being applied to the tree or shrub. When the pressure upon the bulb is relaxed the portion of the bulb not filled with the insecticide or deodorizing substance or fluid is immediately filled with water or fluid from the pipe c, so that the bulb is always filled either with the insecticide or deodorizing substance or a quantity of the same mixed with fluid from the pipe, so that subsequentcompression of the bulb will again act to force the contents thereof into the pipe c to mingle with the fluid therein and be discharged from the nozzle.

To assist in the refilling of the reservoir when the pressure is relaxed, I have, as shown in Fig. 1, formed the perforations in the pipe c by a punching process, leaving lips c2, c3 turned inwardly, as shown, the lip c2 being inclinedin the direction against the flow of fluid in the conducting pipe, while the lip c3 is in the saine direction as the flow of fluid in said pipe, so that when the bulb is relaxed, the lip c2 catches a portion of the water flowing through the pipe and directs it into and to till the bulb, the latter when compressed expelling its contents principally through the forward opening or perforation adjacent the lip c3, the result of this construction being that when the water from the pipe is admitted to fill ythe bulb it enters at the rear end of the bulb and circulates through the latter thoroughly mixing in the inside the deodorizing substance therein before it can issue again into the conducting pipe.

In Fig. 2, I have shown a slightly modified form of apparatus which, however, embodies the same invention as the apparatus Fig. I.

Referring to Fig. 2, the insecticide or deodorizing substance or fluid is placed in an independent reservoir 'm connected with the pipe c by means of a flexible connection or tube m', the external pressure to force the contents of the reservoir into the pipe, being applied by compressing the bulb 'm2 connected with the reservoir.-

As my improved apparatus is to be applied to the ordinary garden hose or to a force pump hose, it will be evident that the spray may be thrown upon the highest shrubs or trees to thus reach all parts of the same, thus making my apparatus an extremely useful and serviceable one.

This invention is not restricted to the particular construction or form of apparatus herein shown in the drawings, and selected as a means of illustrating this invention, for the same may be varied in many particulars and still come within the scope of the invention.

I claim-e l. An apparatus for applying insecticide and similar substances containing the following instrumentalities, vizz-a fluid conducting pipe; an insecticide containing reservoir connected therewith and provided with a filling opening through which to replenish said receptacle when it becomes exhausted, and a closure for said opening, the pressure of fluid in said pipe normally holding back and preventing the escape of the contents of the receptacle therefrom into saidv pipe, and manually operated means to force the coutents of said reservoir into said pipe against the pressure of and to mingle with the fluid flowing therein, substantially as described.

2. The combination with a fluid conducting pipe, of an insecticide containing compressible bulb connected therewith and provided with a filling opening, and a closure therefor, compression of said bulb ej ecting the contents thereof into said pipe against the pressure of and to mingle with the fluid flow ing therein, substantially as described.

3. The combination with a fluid conducting pipe, of an insecticide containing compressi ble bulb surrounding said pipe and communicating therewith through perforatious in said pipe, a filling opening in said bulb, and a closure therefor, compression of the bulb eject-ing the contents thereof into said pipe against the pressure of and to mingle with the fluid flowing therein, substantially as described.

4. The combination with a fluid-conduct ing pipe c, and the threaded heads at its opposite ends, of a compressible receiving bulb d surrounding said pipe and at its ends fitting tightly about the necks of said heads, and perforations c in the said tube within said bulb, the lips c2, c3, and the inlet d2 and its cap, all substantially as described.

5. The combination witha perforated pipe c, and the heads at opposite ends thereof, one of which is provided with a valve, of a compressible receiving bulb surrounding the said pipe, and an inlet for saidbulb, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
